There is indeed more to understanding than memorizing, and you don't seem to grasp that. I've been taking pictures quite likely longer than you have been alive, and I've been using telescopes even longer. I know what I'm talking about. And what have I said that's incorrect?

No what I have had is several peoples opinions, you are the only one that has said anything incorrect so you obviously dont understand, there is more to understanding than memorizing something.

There are millions of 90 year olds that have driven cars all their life but does that mean they can build a ferrari? If I dont grasp something then how can I have made that statement in the first place???

Simply stated, the primary function of a telescope is to collect light. The larger the telescope, the more light it can collect. The more light collected, the fainter and more distant the objects that can be observed.

Getting back to what this was originally about with the help of NASA in the quote above. Which is what I said originally that the bigger lens will have a different effect, therefore even though it has an "equivelant focal length" it is collecting light that is FAINTER, therefore will effect image quality. Only slightly of course. Case closed goodnight!
